Suppose the temperature of the reaction analyzed in Practice Problem 13.14 is increased by 10°C.

(a) What should happen to the number of effective collisions per second? Estimate the new value based on the rule of thumb given in the text.

(b) Why does the number of effective collisions per second change when the temperature is increased?

(c) What is an approximate value for the new rate of this reaction?

Data from Problem 13.14

Consider our substitution reaction between OH^– and CH₃Br. Imagine it is occurring in a solution where there are 1000 collisions every second between OH^- ions and CH₃Br molecules. Suppose only 10% of these collisions are sufficiently energetic to lead to products. Also, assume that the orientation factor is 0.2.
